Altair SimSolid Transforms Simulation for Electronics Enterprise, Enterprise News

The Growing Complexity of Electronics Simulation

Modern electronics are increasingly intricate, with densely packed components that span multiple physical domains. From micro-scale ICs to complex PCB assemblies, engineers must navigate structural, thermal, and electromagnetic interactions to ensure functionality and reliability. Traditional simulation tools often require simplifications or approximations to manage this complexity, leading to potential inaccuracies and prolonged design cycles.

Simulating electronics assemblies involves challenges such as vast dimensional disparities, fine geometric details, and multi-physics coupling. The need to balance accuracy with simulation speed has historically forced compromises, constraining innovation and time-to-market. As miniaturization advances, these challenges intensify, demanding novel approaches.

Altair SimSolid addresses these issues head-on by providing a solver that can handle complex geometries without the need for tedious mesh generation or geometry simplification. This capability allows engineers to capture intricate details and interactions within electronics assemblies more accurately and efficiently than ever before.

Altair SimSolid’s Meshless Multi-Physics Solver

At the core of Altair SimSolid’s innovation is its meshless solver technology, which eliminates the time-consuming tasks of geometry simplification and mesh creation inherent in traditional finite element analysis (FEA). This breakthrough approach accelerates simulation workflows, enabling results in seconds to minutes rather than hours or days.

SimSolid’s solver supports multi-disciplinary physics, including structural and thermal analysis, with full support for complex PCB and IC geometries. By directly working with CAD models, the software preserves geometric fidelity and provides more reliable simulation outcomes, particularly for assemblies with large dimensional differences.

The meshless method also enhances scalability and robustness, allowing engineers to simulate assemblies with thousands of components without the typical bottlenecks of mesh generation. This makes SimSolid uniquely suited for the electronics industry, where design complexity and miniaturization go hand in hand.

Revolutionizing PCB and IC Structural and Thermal Analysis

Structural integrity and thermal management are critical considerations in electronics design. PCBs and ICs must withstand mechanical stresses and dissipate heat effectively to maintain performance and longevity. Traditional simulation techniques often require simplifying component geometries or ignoring minor details, which can lead to inaccuracies in predicting stress concentrations or thermal hotspots.

Altair SimSolid’s advanced solver can analyze full assemblies without simplification, capturing the nuanced mechanical behavior of materials and components. This enables engineers to identify potential failure points and optimize designs for durability and reliability early in the development process.

Thermal simulations also benefit from SimSolid’s capabilities, as it can model complex heat transfer phenomena within densely packed electronic assemblies. Accurate thermal analysis helps prevent overheating issues, ensuring electronic devices operate safely under various conditions.

Advancing Electromagnetic Simulation with Meshless Technology

Electromagnetic compatibility (EMC), signal integrity (SI), and power integrity (PI) are increasingly vital in electronics design, especially as operating frequencies rise and devices shrink. Traditional electromagnetic simulation tools rely heavily on mesh generation, which can be prohibitively time-consuming and limit the ability to analyze large or highly detailed systems.

Altair SimSolid’s upcoming electromagnetic simulation module leverages its meshless solver to streamline this process. By bypassing mesh creation, the software will enable efficient and accurate electromagnetic field analysis across multiple scales, from meters to nanometers, facilitating the resolution of complex EMC/EMI challenges.

This advancement will empower engineers to perform comprehensive electromagnetic assessments rapidly, reduce design iterations, and improve the overall quality and performance of electronic products.

Seamless ECAD-to-Simulation Workflow Integration

A significant hurdle in electronics simulation is the transition from electronic computer-aided design (ECAD) models to simulation environments. This process often involves time-intensive data translation and mesh generation, causing delays and potential data loss or simplification.

Altair SimSolid addresses this by providing a direct ECAD-to-simulation workflow that preserves model fidelity and accelerates simulation setup. Engineers can import PCB and IC designs effortlessly, reducing the barrier between design and analysis phases.

This streamlined workflow enhances collaboration across multidisciplinary teams, enabling faster decision-making and more iterative design improvements. Ultimately, it contributes to shorter product development cycles and higher-quality outcomes.

Leveraging AI and Physics-Informed Neural Networks

The simulation industry is increasingly integrating artificial intelligence (AI) to enhance predictive capabilities and reduce computational costs. Altair SimSolid is positioned to capitalize on this trend by facilitating the training of physics-informed neural networks (PINNs) that can model complex electronics behavior efficiently.

By generating rapid and accurate simulations of intricate electronics systems, SimSolid provides high-quality data sets essential for AI model training. These AI-enhanced models can then predict performance under varied conditions, enabling proactive design optimization and failure prevention.

The synergy between SimSolid’s physics-based solver and AI techniques promises to unlock new levels of simulation speed and accuracy, empowering electronics enterprises to innovate faster and more confidently.
